I am configuring multiple site to site VPN connections using PIX firewalls to terminate (in a hub, spoke configuration). I get to create my next crypto map seq-number on the hub PIX and the firewall collapses. However, the previously configured ipsec tunnels stay active but i cannot use any of the static routes configured to access external networks , NAT fails, internet access etc.
we have tried CLEAR CRYPTO IPSEC SA, CLEAR CRYPTO ISAKMP SA and reloads to no avail.
What could be wrong ? Any help would be appreciated.
I found that when I started my next 'crypto map mapname 10 ...... ' command, the firewall would knock out other connections through the firewall that I had allowed, e.g. stop machines with static routes getting outside, like my proxy server.
Once I had completed the crypto map set, then the connections were once again available.
The workround I used was to cut and past into the firwall the whole specific crypto set all at the same time, eg
Login to the FXOS chassis manager.
